12:20 This is why I installed an oil catch can between the valve cover PCV line and the air-box. During the summer months the can didn't collect much of anything, but when the weather turned colder... WOW. I work from home so I don't do a lot of driving these days, but I did make a 10 hour round trip around thanksgiving. I checked the catch can the other day, and it was full to the top of a nasty yellow foamy gunk. I recommend to anyone with a 2.4L Ecotec (or any DI engine for that matter) put a catch can in your PCV system.

Winter would make sense with the amount of humidity/condensation that forms in the engine before getting up to temp. Again with ring seal issues it just gets worse!

@@buffmotorsports4460 Quick question. I have a 2012 Terrain 2.4l and about 2 weeks ago, out of the blue I started getting P0016/P0017 codes (timing correlation) that immediately reappear when cleared along with a rough idle. A shop confirmed this morning the timing is off mechanically. Thing is I'm at 146K miles and the previous owner had the timing chain assembly replaced at 135k...and the weirdest thing is the chain guide on top that runs along the chain as it travels between the 2 cam sprockets is missing. The bracket is there, but the lip that folds over 90 degrees that they plastic guide attaches to is not there. It's like someone took the bracket and put it in a vice and cut the lip off so that the chain is moving through air with nothing to slap against if there is some slop in the chain. I think this may have been some shady shops "fix" for noise from a chain that was a little loose. In any case that top chain guide is getting replaced with a new part. My question is, I think I can just drain the oil, remove the valve cover and timing cover and rotate the engine to TDC and visually see the timing problem just using the timing marks and colored chain links. If I see that one of the cam sprockets jumped a tooth and is now off, I should be able to rotate it back in line with the timing markers and get everything back in time right?

@buffmotorsports4460

@cswann8 That’s about the gist of things. You’ll need to pull the chain tensioner out of the back side of the block, “reset” it and I believe you’ll gain enough slack in the chain to get it to slip a tooth. I would say go ahead and order a new tensioner to be safe, mine was stuck collapsed and the resetting procedure involves disassembly of the tensioner, not something I’d attempt without specific instructions - which I’m sure you can dig up. Paint marks should line up, some chain sets used a colored chain link, which are hard to spot so rotate the engine back and forwarth to see if you can find them before attempting to slip the chain. Once at TDC, avoid turning the cams too much and do not turn the crank until you know your chain it set. It’s pretty easy to bend a valve. The cast Hexes in the cams should help, you’ll need to take the load against the chain off to achieve your goal and manipulate the cam phaser/sprocket into place. Don’t forget the possibility of the cam solenoids. They could be installed or even hooked up incorrectly as well. Assuming the car was purchased recently with these codes present?

I drive a 2012 Captiva 2.4 in Germany (LE9 engine version). When replacing the timing chain components it's best to use an upgraded front guide with upgraded fixing bolts, obtainable in the US. A new tensioner should always be fitted and oil changes at max.10,000km.

Good video and thanks for including the parts you order and where you got them..

@Juan, I have to correct my previous comment. The tensioner that was different from the OEM part for me was the timing chain tensioner, not the balance chain tensioner.

I searched both part numbers and the images don’t appear to show any noticeable differences... not that that means anything.

@buffmotorsports4460

These are Aluminum with a plastic cover. Unsure of the composition but as a general term they use “plastic” to prolong life of the chain, slides, and quiet the system down all together. Depending on age and the amount of chain slap due to tensioner issues, it’s not an uncommon failure for the plastic to release from the aluminum. Majority of the time, this doesn’t happen. This 2.4 can have issues with one of the tensioner pivot bolts failing. That’s almost certain valve contact.

I read in the description about the 2015 model. We recently purchased a 2015 2.4l Terrain. I’ve been concerned about timing chain issues considering it’s an interference engine. Is this a common issue I should be worried about?

Hey Koricc! Keep up with your oil changes and an eye on your oil level and all should be good. GM made a correction in production that should have eliminated this issue for the 15 - up mode year. There’s always the potential for a freak occurrence, but the timing chain issues are usually a result from oil consumption causing low and dropped oil pressures. (I’ve also seen accusations of the low oil warning not working cause total engine failures) Personally I believe the timing chains were made of soft materials. V-6’s are also notorious for the timing noise. Best you can do is familiarize yourself with your cars “normal” sounds so you can tell when something changes, and keep up with the general maintenance - also so you can notice when something changes. Best of luck!

Funny, we have the same unit... we maintain the hell out of it. It now has a touch under 127,000 and we're going to change the timing chain and guides. Been a fine vehicle and I'm not gentle on 'er at all, we bought it to drive and by god she gets driven. Never revved into the redline though.

It’s good to “clean them out” now and again. Obviously continuously beating on it is going to result in added wear and tear but, if it wasn’t meant to rev to 6,000 rpm GM would’ve set the limiter lower than that 🤣 My wife only has to drive 12-15 mins to and from work which are some of the toughest conditions. Ex. Barely getting warm enough to go into closed loop exhaust gas correction, surely isn’t hot enough to steam off any vapor or condensation, and then a lot of light throttle driving. Oil always smells like fuel and ends up almost a nasty brown when dropped. Poor piston ring seal, PCV system sucks, and low operating temps we undoubtedly end up with diluted and contaminated oil by the time the 3,000 mile mark. So, I use full synthetic and treat it like conventional and change it “early”. Light money on fire, and repeat.

We just did our chain at 189k miles. We had metal that wrapped around the cam sensor and were quoted 8 grand to replace the engine. We put a new chain on, drained the oil and sent it. I hate these Ecotecs. They are 3 grand more expensive than the new Equinox 1.8l motors

The vehicle was very sluggish and lost a bunch of low-end power.

Being an interference engine if it would have jumped timing my repair would have cost a ton more than just my time and a few hundred bucks.

All of the 2.4L GM motors have timing chain issues. If you have one go ahead and schedule your mechanic to replace the chain. This should occur at about the 100k to 110k mile mark on your odometer. If you don't, you will be looking at head work in addition to replacing the chain and related components. Worst case scenario engine overhaul.

@buffmotorsports4460

Last I knew GM didn’t acknowledge the timing chains as an actionable issue like they did regarding the ring seal issues. Wrap your head around this - if you were lucky and got new pistons/rings due to the class action lawsuit it doesn’t cover the chain, guides and tensioners so, they don’t replace the timing components at the time of service. You could have bought and opted for them to install them while it was torn apart but you’d just be putting fast cash in their pockets. They’re going to charge by the book even though they’d already have it disassembled and have to time/reassemble it anyways during the recall.

My wife had a check engine light come on today and she told me her engine was knocking. Shocked at hearing this I went out and drove it down the road and sure enough at lower RPM you can here what clearly sounds like it knocking. It runs rough all the sudden at idle which I figured a misfire is the culprit and caused the check engine light. I was right and Autozone said the code is p0300 which is multi cylinder misfire and said their system said its most likely a VCT solenoid or VVT solenoid. To me, I don't think those would cause this noise although it did start immediately after the check engine light. So I was going to try spark plugs and solenoids BUT after seeing your video I think it might have timing chain issue. has 114k miles so it's probably due for a chain anyway. Any insight?

Dy2 Str33t-King what year 2.4 are we talking about in this scenario? Multi cylinder misfire code being present could mean something simple like spark plugs, or even bad fuel so, no need to assume the worst right away. Now if it jumped time resulting in the uneven idle, perhaps even a misfire - it should have a code/fault present for cam position/angle or VVT efficiency type of code. If the car is older than 2015, I would plan on a timing chain and tensioner service, but would definitely start with the spark plugs and dry gas treatment or a similar product. Be sure to use OEM like AC Delco. This coil over plug system doesn’t favor the iridium plated/tipped spark plugs.

Well, last time I looked Into it GM didn’t recognize the issue with the timing chain system, just the oil consumption from piston and ring defect. So much so that even while addressing the ring seal defect - the timing chain components would be re-used even though everything was already removed and would be a prime opportunity to make the repair. There are a few different things to watch with this engine and they’re all kind of tied to each other. It’s a good little engine…. Until it isn’t. Do a quick google search, they may have changed their settlement or may have even Been hit with additional lawsuits. Best of luck!

Better put your dealership information out there for everyone to go get their work done at! Any time I inquired they were very firm about the oil consumption statute of limitations and never acknowledged the timing chain issue. I specifically asked if and during the piston and re-ring service whether they changed the timing chains. Their response was “it’s not covered in the scope of the repair” but would install the parts if purchased separately. Which is a shame because 80% of this repair is addressed while torn down to rectify the oil consumption issues addressed in the lawsuit.
